Kasco Aeration and Circulation

Kasco Pond and Lake Aerators and Diffusers for aeration only. No fountain display. Highly efficient. For ponds, lakes, sewer ponds, etc. Diffusers recommended for deep ponds. Deep ponds with fish require bottom aeration. Basically, once your pond gets to be deeper than 8 feet, surface aerators can't get down to the bottom. Then you need bottom aerators (diffusers). Circulators fit horizontally and create a slow stream of current. Very efficient. Require little horsepower to work.

As always, we continue to work with HOA's and municipal projects on 30-day terms. Of course, we sell to homeowners the most.

Currently, as of 7-28-2021, Kasco  has about a one-month backlog. This is unusual and we are sorry.

As Kasco Marine states, " Kasco surface aerators dramatically agitate high volumes of water at the surface, maximizing air and water exposure to create valuable gas exchange." These are your best bet when aeration is your chief concern, as they are the most energy-efficient. There is no nozzle to restrict flow! (There is also no decorative fountain pattern.) 

But if your pond is greater than 8-feet deep in most places, your best bet is a diffuser system. Compresser air is is pumped from a shore-mounted compressor to a diffuser at the bottom of the bottom, lake, or perhaps the bottom of a large tank. Micro-bubbles rise to the surfaces carrying large water volumes, increasing water movement and mixing and inducing oxygen transfer.

An option much less discussed but which works very well is the Kasco circulator. The pump is mounted sideways creating a continuous current in the pond or lake, thus eliminating stagnation and removing debris. These are extemely reliable and super-efficient ways to reduce stagnation by keeping the water moving.
